HI Freddy - Nx Witness is sold through a network of distributors and resellers. If you tell us more about yourself/your company we can point you to the right company in your region to provide you pricing.

Waiting for an answer to a question which is similar to Duncan Millers question above. "Is Nx Witness installed on a Raspberry Pi consider NX-Edge? If so does that mean you can only record one camera to a Raspberry Pi?"

As stated above:

2. EDGE Recording License (Nx-Edge)

Enables recording of captured video on ARM servers.

One license channel per camera.

Only one license key could be activated on a device.

Never expires.

Does "Only one license key could be activated on a device." mean per raspberry pi device? This would not be the case I hope. I am looking at running approx 4/5 cameras on a raspberry pi using nx server, this would mean i will need 5 Nx-Edge licences, yes? I hope this is possible.

Until recently, Edge licenses were meant for ARM-based servers (Raspberry Pi and Banana Pi) only. Soon (likely when we launch v4.0) we will allow Professional licenses for ARM-based servers after they have been validated by our team.

Regarding:

"Does "Only one license key could be activated on a device." mean per raspberry pi device?"

This still applies, but this also means you can use more than one camera per RPI, but one license key can contain 4 channels (or 1 or 2 or 3). You can request this up front when you place your order. Currently, the limitations for an ARM-based server is 4 cameras, but likely this will change as well.

For more information, please reach out to you local Nx Witness distributors.

But from v4.0 on, we will support the regular Professional licenses. This means you can add as many licenses as you want and as many keys as you like. That being said, obviously, 60 channels on an RPI won't work, but you could do it.

Also, we will launch an ARM device validation tool at the same time as we launch v4.0. With this tool, you can validate your ARM-based board and if the tool approves the hardware, we will support it.

When you say 5 cameras should be fine, would this include using the PI3+ (Nx Server) for recording motion events simultaneously from the 5 cameras? OR perhaps the PI3+ is not powerful enough?

I would be using my desktop PC as the front end running Nx Witness to view these streams and recorded events.

I saw mention of the Nvidia Jetson Nano being compatible with v4 of your software. Is this platform any more powerful than the PI3+? I see that it uses a similar (same?) quad-core Cortex A57 processor.

The Nvidia Jetson Nano is more powerful, but also an entirely different device. The Jetson boards are mainly developer boards for AI solutions, although you can use them for lots of other applications as well.

The best way to determine if a hardware device is suitable for the solution you're putting together is to test it before deploying.

A few basic recommendations:

Keep your Server CPU usage to 30% or less during normal use (e.g. capturing / recording video) if you never want to see a hardware failure. The RPI3 should be below 30% with 5 cameras at the settings you outline.

The Raspberry Pi has no SATA connectors (assume you're aware of this already!). Recommend avoiding recording to SD cards as they tend to fail rather quickly. If using a Pi suggest you record to an external SAMBA NAS.
